I'm working with the remoting api to migrate a "few" accounts from another panel to ispconfig. To check if an account exists on ispconfig, I need to find it by it's name. For example, I need to check for an alias by it's name and not it's id. Same goes for a mailbox etc. Is there a way to do this via the remoting api, instead of resorting to query directly the ispconfig database? something like the 'mail_domain_get_by_domain' would be nice also for aliases and mailboxes. hints?
